specification.

My invention relates to bakers installations, and particularly to aninstallation cmployin ovens of the general type illustrated 1n myatentNo. 1,135,172, pril 13, 1915.

yThe object of my invention is to improve the lay-out and operation ofthe plant.

In the accompanying drawings- F ig. 1 is a more or less diagrammaticplan of a layout for a four-oven plant;

Fig. 2 is an enlarged side elevation of portion of the plant;

Fig. 3 is a plan of a modified lay-out; and

Fig. el is a vertical section on an enlarged scale on the line 1r-4c,Fig. 3.

ln installations or the type employing ovens and racks of the type shownin my atent above mentioned, it has heretofore heen customary to mountthe racks on wheels so that they may be readily shifted from place toplace about the bake shop. lt not infrequently happens, especially inlarge bake shops, that the racks are not` only shifted from place toplace over various courses, but when not in use, are left standing idlein various positions, where they obstruct the operations of the shop. Bythe present invention the installation 1s such that the course of theracks is limited to certain dened lines of travel, which may be variedwith the needs of any particular shop layout, but in any event preventthe promiscous clogging of the shop area with racks temporarily not inuse. Furthermore, the construction is such that the travel ot the racksis such that they are presented in exact position, not only with respectto the ovens, but also to the proofing rooms. 'lime heretofore lost inadjusting position is thus saved. lt

is a further object of nay-invention to support the racks from over-headrails, thus maintaining the floor uninterrupted and smooth, so that itmay be readily kept clean and sanitary. C

In the lay-out o Fig. l l have Iindicated a battery of four ovens 10,11, 12 and 13, and a corresponding battery o' four proofing chambers 14,15, 16 and 17. .arranged paralle to the oven battery, but spacedsuciently therefrom to permit the manipulation of the racks in themanner hereinafter set forth.

The present plant isdesigned primarily for bread baking. A. moldinmachine 18 is 60 therefore provided, while adJacent it l have indicateda loading table 19, which is preferably of one of the types shown in mya plication of-even date herewith. The ra'c `20, vinstead of beingsupported on running 85 wheels, as has heretofore been the practice,vare suspended by trolleys 21 from over-head tracks 22. The trolleys andtracks may be of any suitable system, although l refer the Londenover-head carrying systemEby reason 70 of its simplicity and efficiencyfor the present purpose.

ln the lay-out indicated, the loading table 19 is located in one cornerofthe work room. lhe track 22 leads therefrom around4 the 75 curve 23 tothe end line 24, from which are branched by switches 25 the three lines26, 2'4" and'28 parallel to the continuation 29 of the end line .24, andat', right angles to the latter.V The parallel lines 26 to 29 inclue0sive are arranged to pass directl through the proofing chambers 14 to17, and7 thence 1n the same direct line to dead ends at the ovens 10 to13. A return line 30 at right angles' to the-dead ended lines 26 to 29is connected e5 to the latter by the switches 31, 32, 33 and 34. Thereturn line 30, assing` between the proofing chambers an ovens, isconnected by the curve 35 to the track reach 22 leading to the loadingtable. An unloading table 9o 36 is arranged in advance of ythe loadingtable and receives the discharge from the racks as' they return to theloading table from the ovens. V v The operation of the plant .is readilyuno5 derstood. Assuming a rack. to have been loaded at the table 19, itis shoved around the curve 23 onto the end line 24, thence to one vorthe other of the parallel lines 26 to 29, which pass through the proongcham- 4'loo bers. The rack is halted in vthe proong chamber sutiicientlylong to prove the goods carried by the rack, and is then advanced fromthe proofing room along the same line to dead-end position in front oftheoven. 105 lf the oven 'at the dead end of any line is alreadycharged, the rack of proofed goods on that line ma be shifted y one ofthe switches 31 to t e return end line 30, and' shunted across thelatter to the switch lead- 110 tables or other devices for v the oven.

ing to an empty oven, into which the shelves from the rack are shoved inwell understood manner. A fter the goods have been baked and the shelvesare drawn out upon a rack, the rack is shifted by one of the switches 31to 34 to the'return end line 30 and moved along the latter to theunloading table 36, where the baked goods are discharged and the rackadvanced to the loading table again for a return of the circuit.

It will be noted that `the arrangement of the track system is such thatwhile the lines are dead ended in front of the ovens 10 to 13, the racksare returned to the line 30 with their front ends faced in the directionof travel, thus obviating the'necessity for turn rectifying theirposition.

In Fig. 2 I have illustrated on a larger -scale an arrangement of thedead-ended lines 26-29 for facilitating lthe charging of As here shownthe terminal section 37 of the dead-ended line ishinged at 38. Its freeend may be lowered by any.

suitable means, such as a cable 39 to incline ,the rack downwardly, `sothat the baking shelves 40 may be readily run off the rack onto the'oven tracks 41 with which the tracks 42 on the rack are brought intoregister A stop 43 for the track section 37 determines the position ofthe rack. Brackets 44 may also be provided on the oven to cooperate withthe extended ends of the rails 42 of the rack for the same purpose, as,well as to guide the wheels of the oven shelves from the rack to theoven rails. As will be noted,

the forward ends of the lower tracks on the rack are extended a greaterdistance than those at the top of the rack to compensate the greaterspacing of the bottom of the rack from the oven in inclined position.The same effect may be attained by varying the projection of the guideracks 44 on the oven ont.

A modified lay-out is illustrated in Fig. 3. Passing fromthe loader 45,which may be vof one of the types shown in my application ofl even date.the racks enter an vLshaped tunnel proofing chamber 46, through whichthey are advanced by an endless chain con- Vveyor 47 having pawls 48(Fig. 4) which engage studs 49 associated with the trolley 50. he track51 passes through the proofing chamber and delivers the racks to the endline 52, from which the dead-ended' lines 53 are branched by switches 54and lead to the battery of ovens 55. The racks are again returned to theend line 52, across the switches 54, and are then shifted inthedirection of the arrow to the unloading table 56, and thence againto theloader 45. In an arrangement such as this, the v,central floor 'space ofthe chamber is kept free from obstruction at all times. The endlessconveyor 47 for advancing the racks through inseam' the roofing chamberis preferably intermittent y operated by a motor 57 controlled bymanually operated switches 58 and 59 at opposite ends of the proofingtunnel.

Various other lay-'outs will readily occur to those dealing with theproblem without, however, departing from what I claim as my invention.

I claim-` 1. In a bakers installation, a battery of ovens, each adaptedto receive a series of removable, superposed, baking shelves, proofingchamber means, a loading table, an unloading table, racks adapted tosupport in superposedposition a group of baking shelves foi-.an oven,trolley 'means for overhead suspension of the racks, and an overheadtrack system for the rack trolleys, said track system comprising acircuit of the loading table, proofing chamber means, ovens, unloadingtable, and thence to the starting point.
